SHOCK ABSORBER.

Application filed May 6, 1919.

To @ZZ fio/10m may concern.'

Re it known that l, ltoiann'r ll. llAssLnr., a citizen oi the llnited iitates, re iding at Indianapolis, in the county ot lilarion and State ot Indiana hare invented certain new thereby reducing; the nninber ot Wearing parts to e 111111111111111 Without disturbing` their it'reedoin @t action.

l further object oit the invention is to limit the action ot a spiral springl associated with a vehicle lest spring to a motion in a vertical plane Without side sony,

l accomplish the above and other objects 'which will heroinatter appear, by the mechanism illustrated in the accompanying diaryrings., in Which- Figure l is :1 view in side elevation ot an end o'l the main traine ot a vehicle with my invention applied thereto. llig. 2 an end 'view o't my device. Fir. 3 a. vertical seetion on the lino 3 3 ot Fig'. 2. Fig. it is a Yioiv partly in top bien and partly in horizontal section, on the lino yit--1lin Fig. 5 is a vicW partly in side elevation and partly in lvertical section, on the line 5-5 in YFigi'.

Referring' to the draivingyjs. 5 is the iront axle t3 the inain traine and 7 :1. vehicle lont spiiu;` o'li usual construction which. is pivotally corinertei'l intermediate its length to the axle in thc usual manner. One end ot lout spring' T is pivotcd directly to traino l and the other end of the lont spring T is connected ivith the traine G 'through thc instrumentality oi' my invention, the embodiment oit which, as here shown, comprises a pair ot spiral springs 8, through the inner convolution ot i which passes a bolt 9. which also passes through the eye l0 at the end of the main traine 6, but is separated from direct contact with the latter by a spacer-sleeve l1. slightly longer than the Width of the eye l0.

rlhe spiral springs 8 are assembled in their respective housings l2. rlfhese housings are connected by bolts 13, here shown Speccaton of Letters Patent.

as three in number and a spacer l-l, located between the said housings.

.A pin l5 is journaled in the spacer lil, and to its projecting ends an irl-shaped link 16 1s rigidly secured and therewith held in a manner to treely oscillate with the pin l5 as a ulcrinn. Bosses 17 on the opposite stems of the link enter the inner convolutions ot the springs 8, thereby relieving' the bolt 9 troni directly bearing on said inner conif'olutions. @ne end ot the bolt 9 is headed and bears agains the adjacent surface of the inner convolution of one spring and the other end of the bolt is threaded to receive a nut 1S, which bears against the adjacent surface o'f 'the inner conif'olution of the other sprino', and, by the intervention of the spacing-sleeve il7 the inner convolutions oi both springs 8 are tightly clamped against link 16 by the tightening oit nut 18. i

he end ot the main leat spring T is journa-led by means ot a pin 19, to ears 20 projecting from the housing l2. Stops 2l are 'termed on spacer lelagainst which the link l@ strikes at the liniits oit its action on its pivot nin l5. rfhese stops 2l prevent the convolutions ot the spiral springs 8 troni striking' against one another at the extreme ends ot their working; range, and thus protect thein from breakage.

r he elongation ot the leaf spring 'i' :is ,itc

deflccts is taken care of through the pivot action of the device as a Whole on the bolt 9 and its journal in the eye l0 ot the trarne 6.

"1 slight torsion takes place in spiral springs 8 es lea/t spring' 7 clongatcs, due to the inner convohltions ol spiral springs V9 heine' clamped endivise along pin 9 and spaccihslee-ve ll..

The chiel'V act-ion of the spiral springs S is the Vvertical play they allord between the ends of the lest spring' 7 and the 'tran e 6. rllhis play is restricted to a. vertical plane h v the tsl-shaped link 16, which yokes over the eye l0 ot the Ytraine 6 at the inner end and over the pin 15 at the outer end, leaving' link lo tree to oscillate vertically .in its journal on the pin l5 in the spacer let. and in the journal on the spacer-sleeve ll in the eye lO ot the traine 6, so that spiral springs 8 and end ot traine 6 are unrestricted as to inotion in a Vertical plane by link l5, but are restrained from moving in any other plane.

To obtain the maximum resiliency and action in the spiral springs 8, they are wound ccccntrically and are mounted in housings 12, whereby the load acts lin a direction opposite to the eccentricity, and the springs havemost of the clearance between the convolutions of the spiral on the unloaded side available for spring action.

The device may be applied to either end of any type of conventional vehicle spring at front or rear 0f the vehicle.

ln the application to the ordinary spring suspension, the device taires the place of regular shackle linlrs, thus eliminating parts tooffset those added.

Having thus fully described my said invention, what l claim as new and desire to secure by Letters Patent, is-

l.. 1n a shock absorber, a frame, a spiral spring pivoted at its axis to said frame, an oscillating housing for confining said spiral spring, and means for pivotally connecting the axis of the spiral spring with the housing at a point eccentrically of the axis of the latter.

2. ln a shock absorber, a frame, a leaf spring, a spiral spring pivoted at its axis to Vsaid frame, a housing for confining said spiral spring, means for pivotally connecting the axis ofthe spiral spring with the housing at a point eccentrically of the axis of the latter, and means for connecting said leaf spring eccentrically with said housing.

3. 1n a shock absorber, a frame, a leafV spring, an oscillating housing for confining vsaid siiral sJrinO means foi` ec'entricallv connecting said leaf spring with said oscillating housing, a radial member connecting the housing eccentrically with the frame, and a spiral spring connecting the housing with the frame.
